Crate prologger 

Prologger

A production-grade, ergonomic Rust logging library with colored output, file rotation, and structured formatting.

Prologger implements the log crate facade, so you can use the standard log::info!(), log::warn!(), etc. macros throughout your codebase.

Quick Start

use log::{info, warn, error, debug};

fn main() {
    // Initialize with sensible defaults (colored console output at Info level)
    prologger::init();

    info!("Application started");
    debug!("This won't show at Info level");
    warn!("Low disk space");
    error!("Connection failed");
}

Builder API

For fine-grained control, use the builder:

use log::LevelFilter;
use prologger::ProLoggerBuilder;

ProLoggerBuilder::new()
    .with_level(LevelFilter::Debug)
    .with_console_default()
    .with_module_filter("hyper", LevelFilter::Warn)
    .init()
    .unwrap();

Features
